The 2004 AFF Championship was the 5th edition of the AFF Championship, the football championship of nations affiliated to the ASEAN Football Federation (AFF), and the last time under the name Tiger Cup. This was the first time a new format had been applied, in which the format was still in use until now. The group stage was jointly hosted by Vietnam and Malaysia from 7 to 16 December 2004, and the top two teams from each group advanced to the Semi-finals and the Final, which was played in a two-leg home-and-away format from 28 December 2004 to 16 January 2005. This was also the final AFF Cup to feature a third-place match, as it was removed in the 2007 edition.
